Abstract:
A method, composition and system respond to ionizing radiation to adjust biological activity. In some approaches the ionizing radiation is X-ray or extreme ultraviolet radiation that produces luminescent responses that induce biologically active responses.

Abstract:
An engine includes a cylinder having a two pistons slidably disposed therein, a port arranged to admit a reactant into the cylinder between the two pistons, and a converter operable with at least one piston to convert mechanical energy of the piston to electrical energy.
Abstract:
One aspect relates to inducing at least one induced X-ray fluorescing photon at a X-ray fluorescence event within an at least some matter of an at least a portion of an at least one individual responsive to an at least some input energy being applied to the at least some matter of the at least the portion of the at least one individual. The aspect can include detecting the at least one induced X-ray fluorescing photon, wherein the inducing at least one induced X-ray fluorescing photon and the detecting the at least one induced X-ray fluorescing photon is configured to be transported portably as a self-contained and self-powered unit.
Abstract:
An electromagnetically responsive element includes sets of arrangements of self-resonant bodies, such as atoms or quantum dots that form an effective dielectric constant, typically at or near a resonance.

Abstract:
A MEM s scanning device has a variable resonant frequency. In one embodiment, the MEMs device includes a torsion arm that supports an oscillatory body. In one embodiment, an array of removable masses are placed on an exposed portion of the oscillatory body and selectively removed to establish the resonant frequency. The material can be removed by laser ablation, etching, or other processing approaches. In another approach, a migratory material is placed on the torsion arm and selectively stimulated to migrate into the torsion arm, thereby changing the mechanical properties of the torsion arm. The changed mechanical properties in turn changes the resonant frequency of the torsion arm. In another approach, symmetrically distributed masses are removed or added in response to a measured resonant frequency to tune the resonant frequency to a desired resonant frequency. A display apparatus includes the scanning device and the scanning device scans about two or more axes, typically in a raster pattern. Various approaches to controlling the frequency responses of the scanning device are described, including active control of MEMs scanners and passive frequency tuning.
